I am looking for guidance on opening an estate account for a relative from MA who died several years ago. We're here to help when a loved one passes away.Knowing where to begin when handling someone else's financial affairs can be overwhelming. Documentation about the account and its owner, including the deceased's full legal name, Social Security number, and the bank account number. Use our Affidavit of Death form to verify the death of a family member and help with the inheritance process. You do have to ensure that you have completed a beneficiary form with your financial institution.
